IMPRdVED APPARATUS FOR CARBURETTING- GAS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it knownthat I, JOSHUA KIDD, of the city, county, and State of New York, have invented a new and useful Improvement in Apparatus for Carburetting Gas; and I do hereby declare that the following is a full, clear, and exact description thereof, which will same, reference being had to the accompanying drawings, forming part of this specification. 1

Figure 1 is a sectional elevation of my invention, the section being taken through the axis of the same.

Figures 2 and 3 are detail plan views of the intercepters' Figure 4 is a side view of a modification, wherein the illuminating-burners are arranged above the carburetting-vessel, which is provided with orifices for small heating-jets below.

parts.

This invention embodies certain improvements upon an invention for which Letters Patent of the United States, N 0. 62,855, were granted to me on the 12th day of March, 1867.

The said improvements consist in the form of the carburtting-vessel, and the interposition of intercepters or disks between the jets or burners and the carburetting-vessel.

In the Letters Patent above mentioned, a carburetting-vessel was employed which contained creosote, or any other (heavy fixed oil or non-volatile hydrocarbon.

Common burning-gas was admitted within the carburetting-vessel, and allowed 'to mingle with gas or vapor evolved by heat from the creosote, or its equivalent.

The heat for evolving such gas was obtained from the ignited jet of the commingled gas and vapor, which jetor jets were arranged under the carburettmg-vessel, which thus received heat from the said g -jet.

The power and, brilliancy of gas carburetted in the manner described being much increased, the apparatus provided a cheap and effective means of illumination; but in order to render its operation perfect, the creosote, or its equivalent fluid, must be heated and vaporizedat or near the top of its vertical column, as otherwise a residual or tarry deposit would result.

In order to provide for this condition, the carburetting-vessel of the said Letters Patent was formed with a central conical chimney, which passed up through the column of fluid in the said vessel, and was provided with a heat-intercepter at or above the top of the said chimney. The heat from the gas, flame, or flames acted upon the upper part of the chimney, which imparted the heat thus acquired to the adjacent surface of oil surrounding it.

The present invention consists in forming the car- Similar letters of reference indicate corresponding ployingan interceptor interposed under the said vessel, and between it and the gas-flame.

The carburetting-vessel can thus be more easily made, and therefore furnished at a less cost than those having the chimneys before mentioned. enable others skilled in the art to make anduse the The'operation and advantages of this form will be more apparent by referring to the drawings, in which- A B is the carburetting-vessel, being composed of two pieces of sheet-metal spun up to the desired form, and united. The form of the part A is not of especial moment, but the. part B, which contains the creosote, (or other oil,) should be or approximate more or less to a hemispherical vessel, or a vessel having a convex form-or external surface. 7

V O is the tube for the entering gas, which latter, in entering, is distributed and diffused bythe disk D, so that it may the more readily commingle with the gas or vapor evolved from the oil or creosote, G. This product then passes down the tube E, and out at the orifices or burners a, and is ignited.

But for the interoepters H I, the heat from the jets would heat the bottom part of B as much as or more than the upper part, and a tarry deposit would result, which would soon unfit the apparatus for use. But by the interposition of the intercepters, the heat is screened from the lower part of the carburettingvessel, and suifered only to act upon the part b 71,- just nnder the ledge or projecting annular lip d, which latter serves to reflect the heat somewhat against the part b b. r v

The carburetting-fluid is thus heated at the top oi its vertical column quite as effectively as when the central chimney is employed, while the cost of the apparatus is much reduced.

' The intercepter may be constructedin various ways, and I desire to be understood as limiting myself to the one shown in the drawings, as my invention contemplates the useof an intercepter or screen of any suitable form or construction.

I have devised a convenient one, which is capable of being adjusted to permit a greater or lessqnantity of heat to act upon the carburetting-vessel. It con- .sists of two disks, H and I, arranged one above the other, the lower one, H, being aifixed to tube E, while the other, I, turns loosely upon it. I

The perimeter of each of these disks is indented, or cut away, as shown. at J J, K K, and when the'disk I is turned, to bring its indented profile K K to coincide with those of the disk H, the heat will act with the greatest permissible eflect upon the carbnretting-vessel A B. By turning these said indentations away from coincidence, (either wholly or partially,) the heatwill be correspondingly screened from the carburettingvessel.

e is a handle or finger-plate, for turning the disk I.

L is the device for supplying the carburetting-vessel with oil.

At fig. 4 is shown a modification of the apparatus, wherein the main or illuminating-burners M M are arranged above the oarburetting-vessel, and the lower burners are employed to supply small heating-j ets, NN.

Having thus described my invention,
